Benefits of technology

[0011] According to the tape end attaching method, since an end portion of tape strip grasped by the tape carrier is attached to the reel hub without using a sticking liquid, no defect takes place in attaching a tape end to the tape reel and stable quality of tape end attaching is provided.
[0012] The tap

Problems solved by technology

A problem encountered by the tape end sticking apparatus is an occurrence of defects in tape end sticking due to excessively large or small spreads of sticking liquid.
Specifically, an excessively large spread f sticking liquid causes the end portion of magnetic tape strip slips relatively to the reel hub and is stuck in an off-center position with respect to the reel hub consequently or fails to stick on the r

Embodiment Construction

[0028] Referring now to the accompanying drawings in detail FIG. 1 is an exploded sectional view of a tape reel 1 according to an embodiment of the present invention. The tape reel 1 comprises a cylindrical reel hub 2 having a center bore 2a formed axially therein which is made of a porous material such as a porous metal, a porous resin or a porous ceramic material and upper or first and lower or second disk-shaped flanges 3 and 4 which are identical in outer diameter. The reel hub 2 has a number of pores distributed uniformly allover the hub wall which permit air to intercommunicate between the interior and the exterior of the center bore 2a of the reel hub 2. The lower flange 3 has a circular center opening 6 surrounded by a circular boss 3a which extends from the inner surface of the lower flange 3 so as to fit tightly in one of opposite axial end openings of the center bore 2a of the reel hub 2 and has an inner diameter sufficiently grater than the circular center opening 6 and ...

Abstract

A tape reel on which a tape strip is wound comprises a cylindrical reel hub having pores distributed allover a hub wall and a center bore formed axially therein and flanges connected opposite ends of the reel hub. The interior of the center bore of the reel hub is depressurized so as thereby to attach an end portion of a tape strip to the reel hub with air sucked in through the pores.

Description

BACKGROUND OF THE INVENTION [0001] 1. Field of the Invention [0002] The present invention relates to a tape reel, a tape cartridge and a method of attaching a magnetic tape strip to a reel hub of the tape reel. [0003] 2. Description of Related Art [0004] Typically, data storage magnetic tape cartridges are commonly used as an external memory device for computer data backup. Such a tape cartridge comprises a cartridge case, a tape reel and its associated parts enclosed in the cartridge case. Generally, the tape reel comprises a cylindrical core formed as a reel hub on which a tape strip is wound and upper and lower flanges radially extending at opposing ends of the reel hub. In a tape cartridge manufacturing line, tape winding is entered by firmly attaching one end of the magnetic tape strip to the reel hub using a tape end sticking apparatus There have been proposed a variety of tape end sticking apparatuses. One of the tape end sticking apparatuses which is known from, for example,...
